• Explore "North Star" Concepts: Pair directly with designers to explore future-state "North Star" proposals, building prototypes in both Figma and code to validate ideas and inform future roadmaps.
• Targeted UX enhancements: Triage, prioritize (with design), and rapidly fix small enhancements, polish items, and bugs reported by customers and internal teams.
• Add Polish and Enhancements: Elevate the user experience by adding thoughtful microinteractions and polish to components and core workflows.

• Hands‐on experience building, maintaining, or contributing to a component library or design system (e.g., using Storybook).
• Excellent communication and collaboration skills, with a proven ability to work effectively with designers and product managers to scope work and find scalable solutions.
• A pragmatic and product‐oriented mindset, capable of balancing technical debt, design intent, and development velocity.

Preferred Skills:

• Experience with UX prototyping and iterating in both high‐fidelity (Figma) and code‐based tools.
